Please recommend a good tree key
 

I am looking for a good tree key and am not happy with the ones I have
looked at so far. I am interested in the area of eastern US and
Canada - mainly, I want the book to cover Ohio, but wider is fine.

When I took a basic botany course at Ohio State circa 1966, I had to
buy a tree key for the course and it was great. Unfortunately, I did
not keep it and I do not recall its name/author. I scanned OSU's
booklist for botany courses this coming term and no tree key book is
listed.

If anyone can point me to a really REALLY good one, I'd appreciate it.
I want a "decision-based" key, not the kind that I have been able to
locate so far.

Here are the five books that I have looked at so far.

The Tree Identification book by Symonds is the best so far, but I'd
really like a more step-by-step decision-based approach that drills
down to very specifics, including bud scars.

Field Guide to the Trees of Britain, Europe and North America

Ohio Trees by Dean

The tree key: a guide to identification in garden by Ed...

Trees: a guide to familiar American Trees by Zim

Thanks in advance.
